plzzz help me out!!!!

Dear Student

 

Given that 20 div = 100 mA

so each div = 100/20 = 5 mA.

 

Initially when the current flow is zero, the ammeter pointer reads 3 div.

After the current is allowed to pass, the pointer is at 17 div after 200 mA,

that means the pointer is at 20 div + 20 div +17 div = 57th div.

 

Negating the initial zero erro of 3 div, the correct reading would be 57 - 3 = 54 div.

 

Hence the value of the current thorugh the ammeter is 54 div x 5 mA = 270 mA.

That is the value of the current flowing through the circuit.

 

We hope that clarifies your query.

 

Regards
